. WIRE FABRIC.

To all whom it may concern.' j

Be it known that we, OsCAR H. STUEWE and l-tnixnotn MARQUARDT, of Milwaukee, Wisconsin, have invented a Wire le ab- 5 ric, of which the following is a specijlication. This invention relates to wire fabric usable for various purposes but intended more particularly for use in bed and couch-bottoms, especially for folding-I )ottoms such as are lo used in Davenports, spring-beds, cots, cribs f and couches. v n y()urol. ject is to provide an improved form of foldable fabric and bedfbottom by a coinbination of twoformsof wire-elements interlocked together in such a manner that the elements are turnable about the joints and the joints cannot become dislocated. p

"d e further aim to produce a better disposititn of the material so that the fabric shall hai c a greater longitudinal than lateral strength corresponding to the direct-ion of 'rain upon the bed-bottom, and which shall present asinooth upper surface giving a bet,- ter and more desirable support to the inattress. 4

Uur invention consists of a combination of two lorlns of wire-elements one of which is bent into a series of alternatingr rectangular loops or. bigghts and the other is substantially straightavitl-i intermediate small loops correspending to tl'ieIoorners of the loops or big'hts on the `tirst element; each of said second ele `ments,serving to unito two of said lirst elements by means of the small loops thereon. As illustrated in the accompanying draws ings, Figure l is a plan view of a part of our ,'iabrrc constituting one corner of a bed or,

couch bottom, Fig. 2 is a longitudinal seetion tlieretl'u'ougrh5 Fig'. .3 is a transverse section thereof; and Figs. 4 and 5 are pers ective views of the respective elements w lich make up the fabric.

fn these drawings evi-ry reference letter and numeral refers always to the same part. lhe aforesaid two elements are designated i respectively A and B; the former being bent at an ang-le a little less than a right angle 'at the points a so as to provide longitudinal laps o and transverse laps a3; and at the ends of the transverse laps are preferably formed crirnps 1,4 which enable the laps ai* to pass around the elen'ients l While the intermediate part lies llush with'the upper sill-face of the fabric. 'lhe element has at interp Specication of Letters Patent. ,Application led. July l, v1908. Serial No. 441,323.

vals corresponding to the distances between the lapsA c3 U-shaped transverse loops b which are turned alternately in opposite directions as shown in lig. Il and are ofsul'li cient opening to allow tuo uires side by side between them. 'l hose loops pass under and around the wires A at the corners c, uniting them together, and u ith the result of producing a fabric all of hose u ires ure'tang'ent to the same plane on the upper surface, and whose strength longitudinally is .reinforced with double the amount of wire that would beused in case elcn'rents A were interlorkcd with. each other directly, thus produciiu;l a better listributi-on of material. A sclvageis formed by means of one el' the elements B embracing the outside element A as show n at B', the loops b being in this rase pressed togethor over the single wire as shoun at b2. llooks as, are formed on the ends of the elements A, l, for engagement with the helical springs C which are connnonly used to support bed-bottoms of this class. y

lt is to be observed that the folding' of the fabric at the joints can readily take place and cannot result in the dislocating' of the joints which has caused trouble in some fabrics, because the crinips o." and the abutment ol' the ends of the laps (1. against adjacent wires prevent these laps from running;l up through the loops b. f

Various changes and nlmlilications in the constructions as herein shown may be made without departing,` from the spirit of our invention, and we wish it understood therefore that the latter is not otherwise limited than by the reasonable scope of our claims,l

Having thus described our invention, what We claim` as new and desire to secure by Letters Patent is:

1. A wire-fabric coniprisimer two alternating sets of elements, the lirst insisting of a Wire bent into substantially rertangrular and alternatelyoppositely directed bic-lits, and the other consisting' of a wire having` at intervals thereon a plurality of short transverse alternately oppositely directed loops engaging the corners of said bights.

2'. A Wire-fabric comprising;1 two alternating sets'of elements7 the 'first consisting of a Wire bent into'substantially rectangular and alternately oppositely directed bigghts7 each bight having a crimp at the corners thereof,

,and the other consisting of a wire having at intervals thereon a plurality of short trans verse alternately oppositely directed loops engaging the corners of said bights.

3. A wire-fabric comprising two alternat ing sets oi elements, the first consisting of a wire bent into 'substantially rectangular and intervals thereon a plurality'of short transverse alternately oppositely directed loops engaging the corners of said bights.

4. A wire-fabric comprising two alternating sets of elements, the first consisting of a wire bent into substantially rectangular and alternately oppositely directed bights and the second consisting of a longitudinal wire engaging and connecting together two of said first elements at the corners thereof, the parts of said longitudinal wire being substantially in one line.

5'. A wire-fabric comprising two alternating sets of elements, the iirst consisting of a wire bent into substantially rectangular alternately oppositely directed bights, and the other consisting of a wire having at intervals thereon a plurality oi short transverse alternately oppositely directed loops engagingthe corners of said bights, all of said wires except the loops and bends thereof lying` substantially in the saine plane. l

6. A wire-fabric comprising two alternating sets of elements, the iirst consisting of a Wire bent into substantially rectangular and alternately oppositely directed bights, and each of said second elements comprising a wire having downwardly bent U-sha )ed transverse loops at intervals correspon in to the lengths of said bights, said U-shape loops being turned alternately in opposite directions Y 7, A wire-'fabric comprising two alternat ing ets of elements, the first consisting of a wire bent into substantially rectangular and alternately oppositely directed bights, and each of said second'elernents comprising a wire having downwardly bent U-sha ed transverse loops at intervals correspon( ing to the lengths of said bights, said Usl1aped loops being turned alternately in opposite directions, each of said loops having an open-v ing sntlicient to allow two wires to lie side by' sim/,eis

side therein in the saine horizontal plane an d each of said loops embracing two bights oi adjacent elements at the corners thereof.

8. A wire-fabric comprising two alternating sets of elements, the iirst consisting of e. Wire bent into substantially rectangular and alternately oppositely directed bights, and the other consisting of a wire having at intervals thereon a plurality of short transverse alternately oppositely directed loops engaging the corners of said bights, hooks bent on the free ends ol' all of said elements, and springs engaging said hooks.

9. A selvage for wire-hibric comprising a wire having a plurality of transverse loops at intervals thereon turned in alternately opposite directions, said loo engaging the wire or wires forming the natural edge of thel fabric.

10. ln combination with a wire-laln'ic containing elements consisting of wires bent into alternately oppositely directed rec tangular bights, a selvage comprising a wire lhaving at intervals corresponding to the corners of said bights and engraving therewith on the outside element oi' fabric a plurality of alternately op ositely turned. transverse loops embracing t ie wire forming said clement.

11. ln combination with a Wire-fabric containing elements consisting of wires bent into alternately oppositely directed reotangular bights, a selvage comprising a wire havlng at intervals corresponding to the corners of said bights and engafing there-v with on the outsideeleincnt o' t ic fabric a plurality of alternately op )ositely turned transverse loops embracing tlie wire forming said element, and a spring connected with the free end of said selvaUe-wire.r

12. A wire-iabric for oedbottoni`s inside up of interlocked elements providing single laps oi Wire extending transversely at 1ntervals across the fabric, and double la is extending longitudinally thereoi', each o" said laps forming a part of a continuous wire on tending from end to end of the fabric.

In witness whereof we have hereunto set our hands this 29th day of June, 1908.
